Whether a data network accommodates 10 personal computers on a LAN or 100 nodes in a global network data communications is the link for greater productivity efficiency and cost savings. This report offers an overview of data communications principles the products and services comprising a data network and the issues facing this dynamic industry. By Thomas Nolle President CIMI Corp. Updated by Datapro staff Basic Principles of Data Communications Data communications is the set of products concepts and services that enable the connection of computing systems. In this context a computing system can be a source of information or information processing or a medium allowing an information user to access such a source. The connection may be one that explicitly makes one system the client and the other the server as is the case with terminal-to-computer relationships. It may also be peer in nature imposing no specific master slave relationship. A collection of such connections supported over a common circuit structure and using shared technological components is called a data network. The elements of data communications are all slaves to the relationship between the business applications for computing the carrier service and standards infrastructure which includes regulatory issues and the technology available. In the past these factors tended to make data communications and data networks slaves of data processing planning. While it is not yet true that networks drive applications more than computers it is certainly true that networks must be considered in designing human-system interactions. In the past it was possible to develop computing applications without any form of data network. That is uncommon today and will be impossible in the near future.
